Feb. 10—A bill divvying up money South Carolina secured from the federal government for its failure to remove plutonium from the Savannah River Site is now headed to the Senate, after a finance ...
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...
The US space agency has routinely had to carry out commands to shut off various science instruments over the years as the 47-year-old spacecraft drains its supply of plutonium.
Criticality accidents are divided into one of two categories: Process accidents, where controls in place to prevent any criticality are breached;; Reactor accidents, which occur due to operator errors or other unintended events (e.g., during maintenance or fuel loading) in locations intended to achieve or approach criticality, such as nuclear power plants, nuclear reactors, and nuclear ...
One of four example estimates of the plutonium (Pu-239) plume from the 1957 fire at the Rocky Flats nuclear weapons plant. The Rocky Flats Plant, a former United States nuclear weapons production facility located about 15 miles (24 km) northwest of Denver, caused radioactive (primarily plutonium, americium, and uranium) contamination within and outside its boundaries.

Over its history, Rocky Flats became the primary plutonium pit production site in the United States. Los Alamos National Laboratory would continue to be used as a pit R&D facility from 1949 to 2013. [27] The Hanford Site also produced plutonium pits from 1949 to 1965. [27] [28] The AEC called Rocky Flats a "Weapon Production Facility" in a 1956 ...
In these the reactor must be shut down and the pressure vessel disassembled to gain access to the irradiated fuel. Plutonium recovered from LWR spent fuel, while not weapons grade, can be used to produce nuclear weapons at all levels of sophistication, [25] though in simple designs it may produce only a fizzle yield. [26]
Tell the whole story of plutonium’s use. Our entire region should be extremely proud of the B Reactor. A massive edifice, built in a year, under tight security.
